   Abstract : Energy harvesting, from ambient vibrations, can be a very effective method for solving the problem with powering electronics were the need for constant power or regular battery replacements is a trouble or an inconvenience. But, since all energy harvesters, using mechanical vibrations, need to operate in resonance in order to generate maximal electrical output, and ambient vibrations usually do not have a constant vibration frequency, this results in the need for efficient self-tuning systems.
